OIL COCK OR VALVE.

SPECIFICATION forming part of Letters Patent No. 727,743, dated May 12,1903.

Application filed AugustZfi, 1902. Serial No. 120,895. (No model.)

To all whom it may concern:

Be it known that we, HENRY E. BRUNNER and EDIE J. PATTERSON, citizens ofthe United States,residing atHaywards,Alameda county, State ofCalifornia, have invented certain new and useful Improvements in OilCocks or Valves; and we do hereby declare the following to be a full,clear, and exact description of the same.

The present invention relates to a certain new and useful oil cock orvalve to be introduced within the oil-supply pipe for conveying oil to ahydrocarbon-burner, the object of the invention being to provide asimple] and effective Valve for controlling or regulating the flow ofoil or hydrocarbon to the burner and for taking up lost motion or wearof the plug and at the same time providing against dirt or sedimentcontained within the oil being conveyed to the burner.

To comprehend the invention, reference should be had to the accompanyingsheet of drawings, wherein- Figure l is a side view in elevation of thevalve or faucet secured to the oil feed or supply pipe, and Fig. 2 is alongitudinal section of the valve or cock.

The numeral 1 .is used to indicate the shell or casing for the valve,which is provided with the upwardly-extending bib 2 and thedownwardly-extending bib 3. he bib 2 terminates in an enlarged interallyscrewthreaded boss 4, which screws on 0 section 5 of the oil feed orsupply pipep The downwardly-extending bib 3 terminates in anoutwardlyflared or bellshaped mouth extension 6, to which is connectedby coupling-ring 7 the union 8. The lower end of this union isinternally screw-threaded and screws onto section 9 of the oil feed orsupply pipe. The union 8 is formed with a circular shoulder 10, which isengaged by the flange 11 of the coupling-ring 7. Within the 'upper edgeof this union 8 is formed a circular groove 12, into which fits and issoldered rim 13 of the strainer 14. (See Fig. 2 of the drawings.) Toprevent leakage between the upper edge of union 8 and lower edge of theoutwardlyfiared or bell-shaped extension 6, a ground joint 15 is formedor provided. The bibs 2 and 3 have formed therein a square oilpassage-way 16, with which registers the square shaped port 17 ofplug orvalve 18. This valve or plug is made tapering and fits within thetapering opening .or seat 19 of the shell or casing 1. The shank or head20 is somewhat larger than the plug or Valve 18 and ex tends through astuffing-gland 21, secured or screwed onto outer end of the casing orshell 1, there being interposed between the gland and said end of theshell or casing a packing 22 in order to prevent leakage at this point.From the shank or head 20 projects the stem 23, which carries akey orhandle 24, by means of which the valve or plug is rotated within itsseat to open and close the passage-way 16. To the inner end of the valveor plug 18 is socured the washer 25, which is held in place by means ofthe nut 26, screwed onto the screw-threaded end. 27 of the said plug orvalve. This end of the plug or valve is inclosed Within or covered bythe cap 28, which screws onto end 28 of the shell or casing.

The shoulder 29 of the cap or cover 28 is arof end 28, so as to preventleakage or escape of oil. a

In order to take up lost motion occasioned by the wear of the plugorvalve 18, it is only necessary to tighten the nut 26 in order to drawthe plug or valve 18 farther into the tapering seat or bore 19 of theshell or casing 1. .Access may be had to this nut 26 by simplyunscrewing the cap or cover 28. To remove the plug or valve, it is onlyrequired to take off the cap or cover 28 by unscrewing the same, removethe nut 26 and washer 25, and thence unscrew the gland 22, when the plugor valve may be removed bodily from within its seat.

Having thus described our invention, what we claim as new, and desire toprotect by Letters Patent, is

An oil-regulating valve or cook for controlling the feed of oil tooil-burners,the same comprising a shell or casing provided with an up-vwardly and downwardly extending bib, an oil passage-way through thebibs, a tapering valve-seat formed within the shell or casing, atapering plug or valve fitted within said seat, a stuffing-gland securedto the outer end of the shell or casing and within which works the heador shank of the valve or plug,

a tightening-nut working on the inner end of the plug or valve, a coveror cap screwed In witness whereof we have hereunto set onto the innerend of the casing or shell so as our hands.

to inclose the ti htenin -nut a ground joint between said ea?) or coxier and the end of the shell or casing, a bell or flared shaped exten- 1sion to the lower bib of the shell or casing, Witnesses:

E. PATTERSON,

a union connected thereto by a coupling-ring,

M. B. TEMPLETON.

and a strainer secured Within the said union.
